2 Claims. (Cl. 68-270) This invention relates to an improved roller scraper attachment for a clothes wrnger to prevent washed fabric from wrapping around the wringer rollers while being passed through the Wringer.

It is among the objects of the invention to provide such an improved wringer attachment which can be quickly and easily mounted on an existing clothes wringer with no material modification of the wringer structure, which can be mounted with equal facility at either side of the wringer as may be desired, which is resiliently maintained in contact with the roller so that it will operatively engage a worn roller and can be moved away from the roller Whenever necessary, which will fit various types of existing wringers, and which is simple and durable in construction, economical to manufacture, positive in operation, and fully effective to prevent washed fabric passed through the wringer from wrapping around the wringer roller to which the attachment is applied.

Other objects and advantages Will become apparent from a consideration of the following description and the appended claims in conjunction with the accompanying drawing wherein:

Figure 1 is a rear elevational view of a clothes wringer with a roller scraper attachment illustrative of the invention operatively applied thereto;

Figure 2 is a transverse cross sectional view on the line 2--2 of Figure l;

Figure 3 is a cross sectional view of a fragmentary portion of the assembly illustrated in Figures 1 and 2 and taken on the line 3-3 of Figure 2; and

Figure 4 is a cross sectional view on the line 4 4 of Figure 3.

With continued reference to the drawing, the clothes wringer illustrated is of conventional construction and comprises a frame having two spaced apart end portions I and II, two juxtaposed, substantially parallel rollers I2 and I3 disposed between the frame end parts I and II and a sheet metal cover I4 extending over the upper ends of the frame parts I and II and the upper roller I3 and secured at its opposite ends to the frame parts.

Each of the rollers I2 and I3 comprises a metal shaft having a sleeve of resilient material, such as rubber, thereon. The roller I2 has a shaft I5 journaled at one end in the frame part I0 and at its opposite end in the frame part I I and a sleeve or covering I6 of suitable resilient material, such as rubber, on the shaft between the two frame parts.

sleeve or covering I8 of resilient material, such as rubberen the shaft I I between the two frame parts. Means are provided in one of the frame parts, for example, the wider part I I, to drive the two rollers I2 and I3 at the same speed opposite directions so that laundered fabric, such The cover I4 is a hollow sheet metal body having an open lowerside, a top wall 2li at its opposite side and spaced apart, substantially parallel side walls 2| and 22 joined to the corre- 'Y spending longitudinal edges of the top wall by arcuately curved portions, as indicated at 23. Each side wall has at its edge opposite the top wall 20 an inwardly turned flange 24, these flanges serving to reinforce and stiien the side walls of the cover.

As the wringer may be of well known construction, a more detailed description is considered unnecessary for the purposes of the present invention.

The roller scraping attachment comprises,

general, a clamp assembly 25, a bracket 26 supported by the clamp assembly, and a blade 21 of exible material carried by the bracket and engageable with the cylindrical surface of one of the rollers I2 or I3, preferably the upper roller I3 at the rear or outlet side of the wringer at a level below the horizontal center of the roller I3.

The clamp 4assembly includes a iiat plate 28 having along yone edge a hinge barrel 29 and having a deep notch 30 extending from the midlength location of its opposite edge inwardly of the plate throughthe major part of the distance 'between the edge having the hinge barrel and the edge through which the notch extends, and" a backing member 3| of hollow rectangular shape and including a fiat planar portion and legs having free ends. The 4backing memberv 3I hasd The roller I3 has a metal shaft I'I journaled at one end in the frame part I0 and at its opposite end in the frame part II and has aA backing member has an aperture in its flat planar portion. A screw 33 extends through the aperture in the back wall of the backing member 3| and through the notch 30 in the plate 28 and receives a wing nut 34 which bears against the outer side of the plate 28 to force the clamp assembly members 28 and 3l together with a portion of the cover 14 received therebetween to rmly clamp the attachment to the cover of the wringer.

The bracket 26 comprises two parts 35 and 36 of which the part 35 is a iiat or second vertical plate of rectangular shape having hinge barrels 31 on one edge thereof and apertures intermediate its width. The hinge barrels 31 receive the hinge barrel 29 therebetween, and a hinge pin 38 extends through the hinge formations 29 and 31 to hingedly connect the bracket to the part 28 of the clamp assembly. The part 36 of the bracket is an elongated, sheet metal structure of L-shaped formation having two legs 40 and 4l disposed at right angles to each other. The leg 40 overlies a portion of the plate 35 and is provided with apertures which receive screws or rivets 42 by means of which the plate portion 35 is rigidly secured to the angular portion 36 of the bracket.

The material of the portion 36 of the bracket is doubled back over the inner surface of the leg 4l to provide a stiffening or reinforcing plate 43 and is doubled back again over the inner surface of the layer 43 to provide a blade retaining layer 44 which is parallel to and slightly spaced from the reinforcing layer 43, to provide a strip receiving space between the plates 43 and 44.

The blade 21 is an elongated strip of suitable, flexible material, such as rubber or leather, and is received in the blade receiving space between the bracket plates 43 and 44 and protrudes at one edge beyond the outer edge of the bracket leg 4l to engage the associated roller. The blade is rrnly secured in the blade receiving space by deforming the plate 44 at spaced apart locations, as indicated at 45, by a suitable tool, such as a center punch.

A helical contractile spring 46 is secured at one end to the leg 40 of the bracket portion 33 at the inner side of such leg by suitable means, such as the screw 41 extending through a loop at the end of the spring and through a screw threaded aperture in the bracket leg and is secured at its opposite end to the clamp screw 35 at the side of the clamp assembly member 3l opposite the plate member 28 by suitable means, such as a loop or eye on the spring extending around the screw 33. This spring resiliently urges the bracket about its hinge connection with the clamp plate 28 in a direction to force the protruding edge of the blade 21 against the surface of the roller i3. The roller scraper attachment may be conveniently formed o f sheet metal, such as light gauge sheet aluminum, except for the screw and nut, the spring and the blade of resilient material. This provides a durable and economical construction and the formation of the clamp assembly is such that the attachment can be mounted on various types of existing wringers.

The invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiment is, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are, therefore, intended to be embraced therein.
